HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 773,488, dated October25, 1904. Application filed December 30, 1903. Serial No. 187,l9 6. (Nomodel.)

To all whom it may concern:

Be it known that I, CHARLES BREN ELLMIRT, a citizen of the UnitedStates, residing at San Francisco, in the county of San Francisco andState of California, have invented certain new and useful Improvementsin Hydrocarbon- Burners, of which the following is a specification.

My invention relates to improvements in hydrocarbon-burners, the objectof my invention being to provide a device of this character which can beused either with refined oils or with distill'ates in cook stoves orranges, in heating-stoves, open fires or grates, furnaces, or hot-waterheaters, which shall be perfectly safe in operation, which will burn theoil or distillate without noise, ashes, odor, or objectionable soot andwith a steady even heat, which can be readily lighted, which will notclog up from any cause, which can be used in a cook stove or rangewithout drilling holes into the stove or otherwise Inutilating the same,and which shall be adjustable for dif ferent sizes and varieties ofstoves.

My invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends hereinafter fully specified,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 isa side elevation of acook-stove equipped with my improved burner. Fig. 2 is a verticallongitudinal section of the upper portion of the stove, showing theburner therein. Fig. 3 is a perspective view of the burner detached.Fig. 4 is a perspective view of an air-closure used with an upward draftof air to the burner. Fig. 5 is an enlarged front view, showing themanner of adjusting the burner.

My improved burner comprises twoprincipal castings, a rectangularbase-plate 1 and an air-conduit 2. The base-plate is formed with aperipheral vertical flange 3, this flange being somewhat higher at oneend, as shown at 4, and the conduit 2 has a downwardly-extending wall 5,formed at its lower edge with slots 6, through which and through theraised flange 1 are passed bolts 7, securing the burner to thebase-plate. By means of these slots the height of the burner can beadjusted as desired with reference to the base-plate. The main body ofthe conduit consists of a horizontal portion 8 for the passage of theair, said portion opening downward at its end, as shown at 9. pipe 10,which is passed through and supported by a perforated lug 11, dependingfrom the conduit and the end of which pipe is preferably bent downwardto discharge the oil. The oil dropping from said pipe falls through theaperture 9, through which the air passes, onto a circularvaporizing-plate 12, supported by upstanding lugs 13, cast upon thebase-plate. Around 'said aperture 9 the conduit flares, as shown at 14,to a diameter substantially equal to that of the vaporizingplate,thereby causing the flames to spread around the conduit. I

It will be observed that the oil-pipe is supported close to the top ofthe air-conduit. The advantage of this'construction is that thereby theoil is maintained as cool as possible in said pipe. The principaldifficulty in constructing an oil-burner for burning California oil isthe tendency of the oil to leave deposits in the pipe, which depositssooner or later clog up the pipe. This deposition takes place morereadily the more the oil is heated in the pipe. It is therefore of greatimportance to keep the oil cool up to the point that it is discharged.The above construction enables this to be done.

In use with a cook-stove the usual grate is removed and is replaced by ametallic plate 15, which is made air-tight by fireclay or other suitablemeans, and the burner is laid thereon. conduit through a small hole inthe plate 16, passing into the stove through the hole 17, usually foundfor fitting the grate into the stove. A valve 18 outside the stovecontrols the supply of oil.

The conduit 2 has a lip or shelf 19 extending forward from its top asfar as the door of the stove, (shown at 20.) The spaces between thesides of the conduit and the sides of the In this conduit is located theoil- The oil-pipe leads upward to the lire-box at the entrance theretoare iilled with lire-clay (shown at 21) to substantially cut off theentrance of air into the lire-box except through the conduit. in orderto adjust for (,li'lierrnt sizes of stoves, the lip or shelf 19 isformed with two transverse grooves 22, di viding said lip into threesubstantially equal sections and rendering it easy to break off one ortwo of the sections, as may be desired, according to the size of thestove.

In use the valve is opened and a small quantity of oil is permitted todrop upon the vaporizing-plate. A piece of paper or other inflammablematerial is then lighted and passed into the air-conduit and allowed todrop upon said vaporizing-plate, igniting the oil. The oil then burnsaround the flange 14, heating the same. The vaporizer quickly becomessufliciently hot to immediately vaporize any oil falling thereupon, andthe perfect combustion of the vapor of the oil is assisted by the heatof the ant-supply thereto, which is highly heated by the flamesascending around the air-conduit. .l find thatit is ofthe greatestimportance to highly heat the air-supply for burning the oil, and mypresentconstruction enables this to be done very eii'ectively. Theflange M at the bottom of the air-conduit spreads the flames through thefire-box. For the purpose of so spreading the flames thevaporizing-plate 12 is also of peculiar construction. On one side it hasan annular concave portion and a central convex portion, the reverse onthe opposite side. It is reversible, so that either side may be useduppermost. The central portion is not higher than the rim, so that itwill be stable in either position. If used in the position shown in Fig.2, the flames will be more concentrated than if used in the reverseposition. In the latter case the flames would be considerably spread.This construction is also useful to conform to the difference in burningheavy distillates or light distillates. The plate is used in theposition in Fig. 52 for burning heavy distillates and in thereverseposition for burning light distillates. This construction is also ofadvantage, as it enables the vaporizing-plate to be tilted slightly todeflect the flames in either direction. Thus by insuring the short barof iron underneath the edge of the burnerplate nearest the stove doorsaid burnerplate may be raised on that side, directing the flames to theother end of the lire-box.

through the opening closed by the stove-door. This is important in twoways-it admits of the burner being placed in an ordinary stove withoutthere being any difficulty in starting the tire through the stove-doorand it also allows the person in charge of the stove to readily watchand inspect the dropping of the oil to ascertain whether it is droppingtoo slow or too fast.

In certain cases it may be desired to have the air-draft enter frombelow instead of from the side, as shown in Fig. 1. In such cases theclosure 25 (shown in Fig. 4:) is desirable. This is a casting having acentral Wall 26 and two lateral walls 27 at right angles thereto, thelateral walls fitting against the sides of the burner below the lip orshelf 19 and the central wall fitting against said lip or shelf. When inthis position, access of air to the conduit is shut off except at thebottom.

I claim 1. A hydrocarbon burner comprising a base, an air-conduitsupported thereon having a horizontally extending portion openingdownward, an oil-pipe in said conduit, and a vaporizing-plate onto whichsaid oil drops, said plate being loosely supported on the base,

and having on one side an annular concave portion and a central convexportion, and the other side beingcurved conversely, the central portionbeing no higher than the rim, substantially as described.

2. A hydrocarbon burner, comprising a base, avaporizing-plate supportedthereon, an air-conduit having a horizontally-extending portion, anoil-pipe in said air-conduit and supported thereby discharging onto saidplate, and means for supporting the conduit and. oilpipe adjustablyrelatively to said plate, said means comprising a vertical flange on thebase, a slotted vertical wall on the conduit,-and bolts through saidwall and flange, substantially as described.

3. A hydrocarbon burner comprising a base-plate, a conduit supportedthereon having a horizontally-extending portion discharging downwardonto said base-plate and having also an upper lip or shelf extending inthe opposite direction from said portion, said lip or shelf being castwith transverse grooves, whereby sections of the same may be broken offto adjust the size thereof, substantially as described.

4. A hydrocarbon burner comprising a base, an air-conduit having adepending lug and a horizontal air-passage opening downward, an oilpipepassed through and supported by said lug, extending in said horizontalportion and discharging over said downward opening, and avaporizing-plate onto which the oil drops, substantially as described.

5. A hydrocarbon burner comprising a base, an air-conduit having adepending lug ITO and a horizontal air-passage opening downward, anoil-pipe passed through and supported by said lug, extending in saidhorizontal portion close to the upper Wall thereof, and discharging oversaid downward opening, and a vaporizing-plate onto Which the oil drops,substantially as described.
